WiBS: A Modular and Scalable Wireless Infrastructure in a Cycle-Accurate NoC Simulator

Network-on-Chip (NoC) has become a fundamental building block in modern Chip Multi-Processors (CMPs) and plays a significant role in their performance. Nevertheless, ever-increasing core counts coupled with shrinking CMOS technology increases communication latency in Electrical NoC (ENoC). Radio frequency enabled Wireless NoC (WiNoC) is one of the promising solutions proposed to supplement the ENoC and form a wired-wireless hybrid infrastructure. However, except for Noxim, there is no other open-source simulation infrastructure for WiNoC exploration. This work implements a cycle-accurate WiNoC infrastructure in a popular ENoC simulator. The infrastructure is modular and scalable for any network size. Among other important features, it implements a broadcast-enabled one-hop communication and a credit exchange mechanism for radio hubs to avoid packet re-transmission. It is a work in progress and hence supports easy integration of new features for exploration.
